Since its completion, Hoover Dam has wowed visitors with its sheer massiveness and its ability to create and hold back a reservoir that covers nearly 650 square kilometers (250 square miles). Yet, perhaps even more impressive is the dam's ability to harness the potential energy stored in the reservoir and convert it to electricity. In this video segment, adapted from Building Big, series host David Macaulay explores Hoover Dam's hydroelectric capabilities.
